One more issue to add. Given the example (which is in the spec):
# html|tr:nth-child(-n+6) /* represents the 6 first rows of XHTML tables */
I think after the following sentence:
# When a=1, the number may be omitted from the rule.
we need to add the sentence:
# When a=-1, the number may be replaced with the minus sign.
Otherwise, the example is not valid.
